Abstract

The invention discloses a visual angle diffusion diaphragm and a display panel. The visual angle diffusion diaphragm comprises a substrate and a refraction protrusion arranged on the substrate. The refraction protrusion comprises a first part and a second part, a first included angle is formed between the first side face of the first part and the surface of the substrate, the second part comprisesa second side face close to the first side face, and a second included angle is formed between the second side face and the surface of the substrate. The first side face of the first part of the refraction protrusion is not parallel to the second side face of the second part; when a light beam emitted by a light source of the display panel is emitted into the refraction protrusion, the propagation direction of the emergent light refracted by the parallel light rays through the first side face is not parallel to the propagation direction of the emergent light refracted by the second side face;therefore, the visual angle diffusion diaphragm has a plurality of modulation angles for one beam of incident light, when the visual angle diffusion diaphragm is applied to the display panel with theconcentrated light shape emitted by the light source, the light shape of the modulated emergent light is more dispersed, and the image quality effect of a large-visual-angle display image is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a viewing angle diffusion film and a display panel. Background technique [0002] With the improvement of the resolution of the display panel, the performance of the brightness of the display panel at a large viewing angle becomes worse and worse. In order to solve this problem, the industry usually adds a viewing angle diffusion film to the display panel, and uses the viewing angle diffusion film to modulate the light of the front viewing angle of the display panel to a large viewing angle, thereby increasing the display brightness of the large viewing angle. [0003] However, the existing viewing angle diffuser film generally only has one modulation angle for a beam of incident light, resulting in a limited ability to modulate the incident light wave. The diffusion effect is poor, affecting customer experience. Contents of the invention [0004] In the first aspe...
